摘　　要：对于一类相对阶大于1的非线性系统,提出了把广义一般模型控制策略和非线性观测器相结合的算法。非线性观测器在线估计控制器参数,利用广义一般模型控制器实现系统控制从而构成自适应控制系统。控制器和观测器参数整定方便,物理意义明确。通过仿真表明,该算法对一类非线性系统实现自适应控制正确有效。The adaptive control algorithm of combining the generalized generic model control （GGMC） scheme with the nonlinear observer was presented for a class of nonlinear systems with relative order larger than 1. With the nonlinear observer estimating the parameters of the controller on line, the adaptive nonlinear control system using GGMC controller was developed. It was very easy for the controller and observer to tune parameters which were very explicit in physic meaning. The simulation results for several typical nonlinear systems were given to expatiate the correctness and effectiveness of the approach proposed.
